【摘要】 在现代微处理器设计中,推断和预测成为开发指令级并行性ILP(Instruction-Level Parallelism)的两种重要技术途径。通过移植GCC可以开发出运行在不同系统平台的高效快速的编译系统。分析了GCC对编译优化的支持,总结了推断和预测在GCC移植过程中的实现方案。更多还原

【Abstract】 Predication and speculation are the key techniques in the design of modern high performance microprocessors in order to expose sufficient amounts ofinstruction-level parallelism to the hardware.By porting GCC,the effective compiler systems fordifferent platforms can be developed.The support of GCC to the compiling optimization wasanalyzed,and the implementation of predication andspeculation on porting of GCC was presented.更多还原
